Back to the scene of his slaughter: Norwegian massacre gunman Breivik in macabre reconstruction as police take him back to island where he killed 69

Pointing his finger like a gun, the monster who killed 69 people in the Norwegian youth camp massacre showed police yesterday how he shot dead his helpless victims.

Wearing a bullet-proof vest to protect him from revenge attacks and on a police leash to prevent his escape, Anders Behring Breivik embarked on a chilling reconstruction of his shooting spree.

The 32-year-old far-Right extremist spent eight hours with detectives on the lake island of Utoya, where on July 22 he carried out his attack on a summer camp attended by the youth wing of the governing Labour Party.

Most of his victims were teenagers or in their 20s.

Earlier he had killed another eight people in Oslo with a bomb.

Breivik reportedly showed no remorse as he described the killings in detail yesterday.

The intensive security operation saw him accompanied by up to a dozen police officers as he walked.

Prosecutor Paal-Fredrik Hjort Kraby said: ‘The suspect showed he wasn’t emotionally unaffected by being back at Utoya, but didn’t show any remorse.

‘He has been questioned for around 50 hours about this, and he has always been calm, detailed and collaborative, and that was also the case on Utoya.’

As the killer retraced his steps, he explained what happened with as little interference as possible from police, the prosecutor explained at a press conference in Oslo last night.

The reconstruction was filmed and will be used as evidence in court, he added. Breivik also took the same ferry he had used to get to the island for his attacks.

The prosecutor confirmed Norwegian media reports that police received several phone calls from Breivik during the massacre, but would not say how the authorities reacted to the calls.

Breivik walked roughly the same route
as the one he took during the shooting spree and explained what
happened with as little interference as possible from police, Mr Hjort
Kraby said.

The entire reconstruction was filmed by police and will later be used in court, he added.

It had
been arranged to avoid the need for a reconstruction in the midst of
the trial and to make the suspect remember more details, Mr Hjort Kraby
said.

The prosecutor also confirmed Norwegian media reports that police received several phone calls from Breivik himself during the terror attack, but wouldn't say how police had reacted.

According to Norwegian daily Aftenposten, Breivik offered to surrender several times and asked police to call him back, but they didn't.

Breivik's lawyer has said he has admitted to the terror attacks, but denies criminal guilt because he believes the massacre was necessary to save Norway and Europe from Muslims and punish politicians who have embraced multiculturalism.

Initial speculation suggested others were involved in the terror attacks, but prosecutors and police have said they are fairly certain that Breivik planned and committed them on his own.

Breivik faces up to 21 years in prison if he is convicted on terrorism charges, but an alternative custody arrangement - if he is still considered a danger to the public - could keep him behind bars indefinitely.
